A parking lot has two entrances. Cars arrive at entrance I according to a Poisson distribution at an average of three per hour and at entrance II according to a Poisson distribution at an average of six per hour. What is the probability that a total of three cars will arrive at the parking lot in a given hour

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

step-by-step explanation:

ur welcome : )

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
